If you own a split king adjustable bed, you’re choosing between two fitted sheet sets: the NON Sticky cotton set with 18″ deep pockets or the Shunjie.Home pack with 600 thread count Egyptian cotton. Both promise a no-slip fit and premium materials, but they take different approaches.
This comparison is for couples who want the right balance of deep-pocket security and luxurious feel. The key trade-off is pocket depth versus thread count. I’ve tested both to help you decide which one belongs on your mattress.

Individual Product Breakdown
I looked at the real-world feel, fit, and value of each set. Here’s my honest take on what you get with each one.

This is the set I recommend for most adjustable bed owners. The 18-inch deep pocket is the real hero, giving a super secure fit on thick mattresses that won’t pop off. I found the 400 thread count long staple cotton to be soft and crisp, and getting a full set with a flat sheet and pillowcases is a major plus. It’s best for anyone who wants a complete, no-fuss bedding solution that stays put. The main limitation is that it’s a lower thread count than the competition, so it feels more crisp than silky.
✅ Pros
- Super secure 18-inch deep pocket fit
- Complete 5-piece set includes flat sheet
- OEKO-TEX certified for peace of mind
- High customer rating with over 1,500 reviews
❌ Cons
- Lower 400 thread count than some options
- You only get one color choice per order

If your priority is a plusher, denser feel, this 600 thread count Egyptian cotton set delivers. The sateen weave is noticeably smoother and has a slight sheen. The 16-inch pocket is still deep enough for most mattresses, but I found it a bit less forgiving than the 18-inch option on very thick beds. This is best for someone who already has a flat sheet and pillowcases they love and just wants an upgrade in fitted sheet quality. The clear limitation is that it’s only the two fitted sheets, so you need to supply the rest.
✅ Pros
- Luxurious 600 thread count Egyptian cotton
- Competitively priced for the material quality
- OEKO-TEX certified and very breathable
- Slightly higher 4.4-star customer rating
❌ Cons
- Only includes two fitted sheets (2-pack)
- 16-inch pocket may not fit the very deepest mattresses
Which One Should You Buy?
There isn’t a single best sheet for everyone. My recommendation changes based on your mattress depth and whether you need a full bedding set or just the fitted sheets.
NON Sticky cotton Adjustable Split King Sheet Set is right for you if…
- You have a very thick mattress or mattress topper and need the full 18-inch deep pocket security.
- You’re starting from scratch and want a complete 5-piece set with a flat sheet and pillowcases.
- You prioritize a no-pop fit on your adjustable bed over a super high thread count feel.
Shunjie.Home Split King Egyptian Cotton Fitted Sheets is right for you if…
- You want the plush, silky feel of 600 thread count Egyptian cotton on a budget.
- You already own flat sheets and pillowcases you love and just need replacement fitted sheets.
- Your mattress is standard to moderately deep (16 inches or less).
❌ Who Should Skip All of These?
If you don’t have a split king adjustable bed, these specific sizes won’t fit. Also, if you strongly prefer a percale weave over sateen for a crisp, cool feel, you should look for a different material.
For most people with an adjustable bed, I recommend the NON Sticky cotton set. The 18-inch pocket and complete bedding solution solve the biggest headaches, and the 400 thread count cotton is still plenty comfortable.
Frequently Asked Questions
Which sheets fit a thicker mattress better?
The NON Sticky cotton sheets are the clear winner for thicker mattresses. They have an 18-inch deep pocket compared to the Shunjie.Home’s 16-inch pocket. That extra 2 inches makes a big difference if you have a pillow-top, a thick mattress topper, or a very plush mattress, ensuring the sheets stay securely tucked.
Are the Shunjie.Home sheets softer because of the higher thread count?
Yes, the Shunjie.Home sheets feel softer and plusher right out of the package due to their 600 thread count Egyptian cotton. The NON Sticky cotton sheets at 400 thread count have a more crisp, hotel-style feel. If a silky-smooth hand-feel is your top priority, the Shunjie.Home sheets deliver that.
Which set is the better value for the money?
It depends on what you need. The NON Sticky cotton set is a better value if you need a full bedding set, as it includes a flat sheet and two pillowcases. The Shunjie.Home set is a better value if you only need fitted sheets and want premium Egyptian cotton. Check the current price on Amazon for each to see which fits your budget.
Do both sheet sets work on Sleep Number or other adjustable beds?
Yes, both are specifically designed for split king adjustable beds. The key is the split design (two separate Twin XL fitted sheets), which allows each side of the bed to move independently. The NON Sticky cotton set is even marketed for Sleep Number beds, but both will function the same way.
Which sheets are easier to care for and less likely to shrink?
Both are machine washable and claim to be fade and shrink-resistant. In my experience, the 100% long staple cotton in the NON Sticky set and the OEKO-TEX certification on both indicate good quality control. I didn’t notice significant shrinkage with either when following the cold wash, low dry instructions.
Is the Egyptian cotton in the Shunjie.Home sheets worth it over regular cotton?
If you appreciate a denser, more luxurious feel, then yes, the Egyptian cotton is worth it. It typically results in stronger, softer fibers for a plusher sheet. However, if you prefer a cooler, crisper feel or have a very deep mattress where the 18-inch pocket is non-negotiable, the NON Sticky cotton’s long staple cotton is the better choice.
My Final Verdict
After comparing them side-by-side, I declare the NON Sticky cotton Adjustable Split King Sheet Set the overall winner. Its 18-inch deep pocket provides the most secure fit for adjustable beds, and the complete 5-piece set offers the best convenience. The Shunjie.Home sheets are the runner-up, best for buyers who prioritize the plush feel of 600 thread count Egyptian cotton and only need fitted sheets.
If you’re on the fence, let your mattress depth decide. If it’s over 16 inches thick, go with NON Sticky cotton. If it’s standard depth and you crave luxury, choose Shunjie.Home.
